they are two years old, and it is exceptional for them to have 

 young when one year old ; but those that have been imported 

 to Alaska foal at one year old, and it is exceptional for them 

 to go until they are two. Also in Alaska a large percent has 

 twins. 



"They are inferior to dogs for travelling, being able to 

 make only about one half the distance of a dog team in a day, 

 and they are unable to endure the continuous work of dogs."

3. Paralces alces (Linn.). 

 ELK. 



The Elk has apparently disappeared from the region bor- 

 dering the Okhotsk Sea, but still exists further inland. No 

 specimens are included in the collection. 



"Russian name, Los. The Russians at Gichiga say that 

 Elk were formerly found at Parane on the head of Penginski 

 Gulf, and that a few are still taken near Yamsk. Mr. Jochel- 

 son says that they are abundant in the valley of the Kolyma 

 River." N. G. B. 



4. Moschus moschiferus Linn. 

 MUSK DEER. 



The collection contains a single specimen of Musk Deer, a 

 young male, collected by Mr. Jochelson in the Verkhoyansk 

 Mountains, near the junction of the Yana and Dulgulach 

 Rivers, Yakutsk, Siberia. The general color above is black- 

 ish brown, strongly varied with yellowish gray; ears blackish, 

 fringed internally with white; throat and breast dusky 

 strongly varied with white. The collector's measurements 

 are : Head and body, 780 mm. ; tail, 30 ; hind leg, 468 ; girth, 490. 



It is hardly probable that the north Siberian form, repre- 

 sented by the present specimen, can be subspecifically the 

 same as true moschiferus of the Himalayas, but lack of mater- 

 ial prevents a critical consideration of the subject. P alias's 

 name Moschus sibiricus is apparently available for the north- 

 ern form, should it prove separable.
